What is conductivity
The electrical conductivity of milk measures the ability to conduct current, related to the concentration of ions (sodium, chlorides) in the fluid. An increase in conductivity may indicate an inflammatory state of the mammary gland.
Conductivity and mastitis
Direct relationship
In the presence of mastitis (especially subclinical), there is an increase in ions in the milk due to the permeability of cell membranes. This causes a rise in conductivity.
Early indicator
The conductivity value increases before the appearance of clinical symptoms. Constant monitoring allows the timely identification of the first signs of infection.
Detection systems
Sensors in the milking parlor
Integrated into lactometers or milking robots, they detect the conductivity of each quarter in real time.
Continuous monitoring
Data are recorded and analyzed by management software, which signals anomalies and identifies concerning trends.
Advantages for the farmer
- Early diagnosis
- Timely and targeted interventions
- Reduction in antibiotic use
- Improved animal welfare
- Higher milk quality
Conclusions
Monitoring conductivity is a simple but powerful tool for preventing mastitis. Digital technology now allows precise and personalized surveillance, protecting herd health and farm profitability.
